The Saturn SX1 FPGA module is optimized for DSP applications. It offers high-performance yet low cost DSP FPGAs, large and high-bandwidth memory, LVDS I/Os and a USB 2.0 High-Speed device interface.

The Saturn Starter base board in conjunction with the Apollo evaluation platform enables rapid prototyping. A variety of Apollo expansion boards is available providing many different functions.


  • Features the largest Xilinx low-cost FPGA optimized for digital signal processing
  • Provides a FX2-based USB 2.0 High-Speed interface with data rates up to 30MBytes/sec. Linux and Windows drivers available.
  • Comes in handy credit card form factor
  • Only requires a single supply voltage


  • Vast amount of parallel processing power for DSP applications (up to 126 multipliers at 250 MHz = 31.5 GMAC/s)
  • High-bandwidth data I/O due to the large number of available LVDS pairs
  • Simple and low-cost integration, with standard interfaces (USB, UART) and a single supply voltage
  • Many IP cores are available from Xilinx, Enclustra and third parties
